Abstract

593355 Disclosed is a nozzle for a bladeless fan assembly for creating an air current, the nozzle comprising an interior passage for receiving an air flow, a mouth for emitting the air flow, and a plurality of stationary guide vanes located within the interior passage. Each vane directs a portion of the air flow towards the mouth. The nozzle defines an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The interior passage is shaped to divide a received airflow into two air streams. The guide vanes comprises two sets of guide vanes each arranged to direct a respective air stream towards the mouth.
